1. 獲取應用的連結地址

開啟iTunes，搜尋應用的名稱，點選倒三角按鈕，選擇拷貝連結

2. 跳轉

1、iOS原生應用跳轉：（通過AppStore App，推薦使用）

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"app的連結"]];

2、html5應用跳轉, 這裡分為兩種方式。一種直接寫個\ 標籤，一種是利用js

<a href="itms-apps://itunes.apple.com/cn/app/jie-zou-da-shi/id493901993?mt=8">更新</a
 
>

window.open('itms-apps://itunes.apple.com/cn/app/jie-zou-da-shi/id493901993?mt=8');

3.應用內直接跳轉到appstore，需要新增StoreKit,framework系統庫，需要實現下面的代理方法

SKStoreProductViewController *storeProductViewContorller = [[SKStoreProductViewControlleralloc] init];
//設定代理請求為當前控制器本身
storeProductViewContorller.delegate
 
 = self;
//載入一個新的檢視展示
[storeProductViewContorller loadProductWithParameters:
 //appId唯一的
 @{SKStoreProductParameterITunesItemIdentifier : @"1049660516"} completionBlock:^(BOOL result, NSError *error) {
     //block回撥
     if(error){
         NSLog(@"error %@ with userInfo %@",error,[error userInfo]);
     }else
 
{
         //模態彈出appstore
         [self presentViewController:storeProductViewContorller animated:YES completion:^{

         }
          ];
     }
 }]

//取消按鈕監聽
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController{
    [self dismissViewControllerAnimated:YES completion:^{

    }];
}

補充：跳轉到評價頁面：

int appID = 1118301512;
    NSString *str = [NSString stringWithFormat:@"http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=%d&pageNumber=0&sortOrdering=2&type=Purple+Software&mt=8",appID];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
